2004 kia spectra, check engine light is on and wont go off to pass inspection, so what can be wrong with car, but it runs good.

Can you tell me what code comes up or do you not have a code reader? If you just want to turn check engine light off, you can disconnect the battery for a few minutes and this will usually clear the engine code, but it will not cure the problem. The light will come on again after 40 or more KM's.

170000 mile maintenance required light came on

Call your local auto parts shop and see if they will loan you a ODB II code reader. O'Reilly, Schucks, Checker and Kragen loan them to you at no charge (you just give them your license while you use it in the parking lot). This will plug in under your dash and read the codes which have caused the problem. It will also allow you to reset the codes and turn the warning light out. If the problem still exists the light will come back on after you start or drive it awhile.

Auto parts stores make their money selling you the parts to fix the problem yourself and are generally glad to loan you the reader to use in their parking lot. It is a nice service they provide and is a good thing to learn how to use. The store staff is almost always willing to show you how to use it and help in determining what the codes really mean in plain english.

2000 E-350 V-10. P0174 with exhaust fix

Before I even finished reading this i knew you had a clogged cat. If you have fixed everything you mentioned i would lean towards a clogged cat. This is a large reason this code pops up.

To check this you could pull that cat out and drive around and see if the code comes back, make sure to stay away from the police though.
